Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Green Tomato Pickle
Ingredients
Directions
Prepare the vegetables
Combine the sliced green tomatoes, onions, and chopped peppers in a large pot.
Add a handful of coarse sea salt, cover with water, bring to a boil, and cook until tender but not broken.
Drain the vegetables through a colander.
Pickle and jar
Heat enough vinegar to cover the vegetables until scalding hot.
Place the drained vegetables in a jar and pour the hot vinegar over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the pickle and absorb the vinegar's tang as it sits.
- Onions
- Add sweetness and savory depth that balances the sharp vinegar.
- Peppers
- Contribute mild heat and fresh, vegetal flavor to the pickle.
- Vinegar
- Provides the acidity that preserves and sharpens the pickled vegetables.
The step that matters
Cook until tender but not broken. Cooking the vegetables just enough softens their cell walls so they take up the vinegar, while overcooking causes them to fall apart and turn mushy, leaving a limp, cloudy pickle.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, vinegar):
- Capsicumfits better
- Cucumberfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
